Problems solved by technology

[0002] At present, the rubber processing technology is usually directly granulated after crushing. The particle size of the crushed rubber material is still relatively large, and most of the impurities are still wrapped in the rubber block, which is not conducive to subsequent processing. The processed rubber contains excessive impurities and is clean. The density is low, which cannot meet the requirements of high-quality tire production technology, and even if the number of granulation is increased, the effect of reducing the impurity content and improving the cleanliness is not obvious

Embodiment 1

[0020] Place 3 crepe machines with a specification of 450×1000, 3 corrugators with a specification of 350×1000, 1 hammer mill with a specification of CM-550, and 1 vibrating screen with an unlimited specification On the rubber processing line;

[0021] Step 1. Put large pieces of different grades of rubber into the crusher, and spray water at the same time to wash the rubber blocks through the rotor and stator inside the crusher. During the crushing process, the impurities and ash inside the rubber blocks follow the water flow filter out;

[0022] Step 2. The rubber material coming out of the crusher enters the vibrating screen and sprays and washes at the same time to further remove impurities and ash inside the rubber material to improve the consistency of the rubber material. The vibrating screen classifies and screens the rubber material and crushes it. The rubber material whose size meets the specifications enters the crepe process, and the rubber material whose crushed ...

Abstract

The invention discloses a natural rubber processing technique which comprises the following procedures: crushing, creping, pelleting, drying, weighing and packaging. The natural rubber processing technique is suitable for mixing and processing rubber materials of different grades, a screening procedure is additionally set after the crushing procedure, and a hammer-crushing procedure is additionally set after the creping procedure. The invention aims to provide the natural rubber processing technique which is capable of enabling the processed rubber to be relatively high in consistency, stability and cleanness.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a natural rubber processing technology. Background technique [0002] At present, the rubber processing technology is usually directly granulated after crushing. The particle size of the crushed rubber material is still relatively large, and most of the impurities are still wrapped in the rubber block, which is not conducive to subsequent processing. The processed rubber contains excessive impurities and is clean. The degree of concentration is low, which cannot meet the requirements of high-quality tire production technology, and even by increasing the number of granulation, it is not obvious to reduce the impurity content and improve the cleanliness. Contents of the invention [0003] Aiming at the deficiencies in the above-mentioned prior art, the object of the present invention is to provide a natural rubber processing technology capable of making the ...
